Japanese december 3d icon set

Create an icon collection that represents the objects, symbols, and mood of the month of [Month]. They should be unified under a single theme. The background is pure white. Place the name of the month, "December", at the top center of the image as a minimal and balanced title. Position it symmetrically on a grid, visually integrating it with the overall design. The icons should be rendered in a colorful yet subdued 3D style, using textures and atmospheric lighting appropriate for the season. They should reflect the essence of December in Japan. Maintain consistent proportions, materials, and visual language across all icons and the title.
